To aZZ whom it may concern.-

Be it known that 1, CHARLES EYSTER, a

citizen of the United States, residing at Holcomb, in the county of Ogleand State of Illi-- nois, have invented certain new and usefulImprovements in Looking Devices for Safe- Doors, of which the followingis a specification.

The object of this invention is to construct a locking device for thedoor of asafe or vault in which the locking-bolts are controlled andoperated by the combination knob or lever.

In the accompanying drawings, Figure 1 is an inner face view with thebolts in theirlocked position. Fig. 2 is a similar view in which thebolts are in their unlocked position. Fig. 3 is a horizontal sectionthrough the combination-dial and the bolts in their locked position.Fig. 4' is a similar view in whichthe bolts are in their unlockedposition. Fig. 5 is avertical section through the combination-dial andthe bolts in their locked position. Fig. 61s a similar view in which thebolts are in their unlocked position. Fig.

7 is a vertical section through the cams on dotted line a, Fig. 1. Fig.8 is an isometrical representation of the spindle for operating thecombination and boltwork.

The casing '1 of a safe or vault has an open end 2, to which is fitted adoor 3, having a hinged connection with the casing. To the inner face ofthe door is secured a frame or rim 4. A beam 5 has a pivotal connectionat one end with the rim and guided by the loop 6. The sliding bolts 7are supported by the rim and project into openings in the casing.Vertical bars 8 and diagonal bars 9 connect the bolts. A link 10 has oneend pivotally connected with the beam 5 and its other end pivotallyconnected with one of the vertical bars 8. As the beam 5 is moved on itspivotal support the link will impart a reciprocating movement to thebolts 7. The free end of the beam 5 supports a combination mechanism forcontrolling the moving and sliding bolt 11, which is operated by thelever having projections 12 and 13 of different diameters.

Through the door is formed an opening within which is located a spindle14, having a knob 15 and a graduated dial 16 secured to one end. To itsother end are secured a toothed wheel 17 and a collar having acircumferential groove 18. The end of the collar has a recess 19 and tworadial openings 20 and 21 to receive the projections of thecombinationlever. v

To the free end of the pivoted beam 5 is fitted a bell-crank levercomposed of the arms 22, pivotedto the beam, a slotted arm 23, and anarm 24, having an opening 25. A bailshaped link has a connection withthe upper surface of the free end of the beam by the clamp 26. The end27 of the link is located in the slotted arm 23, and the downturned end28 is located in the circumferential groove 18" of the collar secured tothe spindle 14.

To the inner face of the door is secured the loop 6, surrounding thebeam 5, and has two openings within which are located the journals 29 ofthe cams 30 and 31. The other ends 32 of the journals are supported inthe door, and the journal supporting the cam 30 has a toothed wheel 33secured thereto, and the journal supporting the cam 31 has a toothedwheel 34 secured thereto. An intermediate toothed wheel 35 is supportedby the door' and meshes with the toothed wheels 33 and 34. The cam 31 islocated above the cam30 beneath the pivoted beam 5.

' The operation of' my improvements is as follows: With the parts in theposition shown at Figs. 4, 6, and 7, the spindle is pushed in until itsrecessed end engages the lever of the combination-lock, and at the sametime the bell-crank lever will be moved on its pivotal connection withthe beam and its end 24 located between the free end of the beam and theside wall of the casing. By turning the knob 15 the combination-lockcontained in the beam will be manipulated and the latch 11 will beforced out through the opening 25 in the bell-crank lever into anopening in the side wall of the casing, when the pivoted beam will belocked in connection 5 will also be held against lengthwise move mentand the parts will appear as shown at Figs. 1, 3, and 5. In unlockingthe door the ICC combination-lock supported by the pivoted beam is setup by manipulating the knob 15 and graduated dial 16 until the latch 11is withdrawn. Then by drawing out on the spindle the toothed wheel 17,carried thereby, will mesh with the intermediate toothed wheel 35, andby turning the knob 15 the toothed wheels 33 and 34; and cams carriedthereby will be turned so that the cam 31 will permit the cam 30 toraise the beam on its pivotal connection with the inner frame until thebeam appears as shown at Fig. 2, and the link will become disengagedfrom the circumferential groove 18, formed in the collar supported bythe spindle. The raising of this beam will through the link 10 withdrawthe sliding bolts from their engagement with the casing of the safe-orvault, when the door can be opened. After closing the door by turningthe toothed Wheels in the reversed direction the lower cam 30.willpermit the beam to drop, and should it stick the upper cam 31 will forceit down into place and move the bolts into place and cause the link toengage the circumferential groove IS, and by pushing in on the spindleits recessed end will receive the lever of the combination-locksupported by the beam and will at the same time move the bell-cranklever so that the opening 25 will be in line with the latch 11, and bythrowing off the combination-lock the latch will protrude through thebell-crank lever into the opening in the casing and hold the doorlocked.

The openings in the end of the collar supported by the spindle 14 are ofdifferent dimensions corresponding to the projections extending from thecombination-lever supported by the pivoted beam 5 in order that thespindle may engage the combination-lever in the same relative positionwhich it occupied before it was separated therefrom.

The end of the beam 5 near its pivot projects into the casing when thebeam is in its locked position, which serves to prevent the opening ofthe door, and its free end rests upon a support 36, and a pin 37,projecting from the under face of the beam, enters a hole in thesupport, which prevents lateral movement of the beam and holds its freeend in proper position so that the latch may enter the opening in thecasing.

The combination mechanism for operating the latch 11 is not shown, assuch construction is old and well known.

I claim as my invention- 1. In locking mechanism for safe-doors, a setof boltwork, a combination-lock, means for operating the boltwork andcombinationlock, and capable of disengagement with both and move intoengagement with either.

2. In looking mechanisms for safe-doors, a set of boltwork, a movablebar operating the boltwork, a combination-lock carried by the bar, andmeans for operating the combinationlock and moving the bar.

3. In locking mechanism for safe-doors, a set of boltwork, a movable baroperating the boltwork, two cams for raising and lowering the bar, andmeans for moving the cams.

4. In locking mechanism for safe-doors, a set of boltwork, a movable baroperating the boltwork, two cams for raising and lowering the bar, aspindle extending through the door and connected with the cams.

5. In a locking mechanism for safe-doors, a set of boltwork, a movablebar operating the boltwork, a combination-lock carried by the bar, thebar capable of being locked against movement.

6. In a locking mechanism for safe-doors, a

set of boltwork, a combination-lock, a spin-- dle havinga slidingengagement with the door and adapted to be moved into or out ofengagement with the boltwork or combinationlock.
